Abstract

A light-emitting device includes first and second portions. The first portion includes a light-emitting element, a wavelength conversion member, and a first reflective member covering lateral surfaces of the light-emitting element and the wavelength conversion member. The second portion includes a light-transmissive member disposed above the wavelength conversion member via an air layer, and a second reflective member disposed around the light-transmissive member. An upper surface of the first reflective member has a first upper surface disposed around the wavelength conversion member and a second upper surface disposed outwardly of the first upper surface. A lower surface of the second reflective member has a first lower surface disposed around the light-transmissive member and a second lower surface disposed outwardly of the first lower surface. The air layer extends between the first upper surface of the first reflective member and the first lower surface of the second reflective member.
